Sep 25, 2011 - 13Cubed has introduced APG 2Go 1.0, which generates passwords with two, three, or four random common dictionary words. It displays length and approximate bits of entropy. These types of passwords are among the most difficult to crack during brute-force attacks. Mathematicians have proven that the length of the password is often more important than the complexity. A password based on four common English words is much easier for someone to remember, and at the same time secure.
